The Office of the Attorney General issued a subpoena to the A.B. Won Pat Guam International Airport Authority, seeking documents related to the airport’s investigation into a 2016 shooting of an unarmed motorcyclist by an airport officer. The airport has yet to hand over the requested documents, according to Assistant Attorney General Jeremy Kemper.

Kemper told the Superior Court of Guam that the airport was subpoenaed in September, to no avail. Prosecutors want the airport's documents as evidence in the criminal case against airport police officer Vincent Castro. Castro is charged with aggravated assault and reckless conduct in the June 2016 shooting of unarmed motorcyclist Joshua John Untalan Mesa.

The airport in August 2016 cleared Castro and a second officer involved of any wrongdoing. Airport officials said Castro responded with the appropriate use of force when he fired his weapon at Mesa.

Mesa was on a motorcycle without license plates in the Home Depot parking lot when airport officers asked him to turn off the motorcycle, court documents state. Mesa reportedly fled, and the airport officers pursued him to Finegayen Road, also known as Hamburger Road, documents state.

Officers parked their car in an effort to stop Mesa, but Mesa drove around the car, which is when Castro shot at him, court documents state. Mesa was shot in the buttocks, causing him to lose control of the motorcycle and crash on Hamburger Road. He was hospitalized for his injury.

Castro’s lawyer, Curtis Van de veld, said on Thursday that he hasn’t received documents related to the airport’s investigation, despite asking for them months ago.

“As I have often seen, the Guam Police Department doesn’t fully perform its functions, the investigations very well. Sometimes, the airport also doesn’t get everything, but between the two there’s the likelihood of a better opportunity for receiving information. It’s just that I don’t have those things,” Van de veld said.

“This case involves a motorcycle charging at my client, he responded, and in drawing his weapon, he fired his weapon, and that happens with rapid responses based upon habitual training, and I wanted the records about that because that would be important.”

Kemper said a subpoena was served the airport police in September for the documents but the documents still weren’t given to prosecutors. Kemper said he will follow up with the airport.

Superior Court of Guam Judge Michael Bordallo told Van de veld to send prosecutors a list of documents he has yet to receive related to Castro’s case, and he gave the prosecution 30 days to send that information to Van de veld.

Castro isn’t the only one charged in connection with the shooting.

Mesa also faces criminal charges in connection with the incident but his case is separate from Castro’s case. Mesa is accused of receiving a stolen motorcycle, driving under the influence of a controlled substance, eluding a police officer and other crimes.
